The LM109 series are complete 5V regulators fabricated on a single silicon chip. They are designed for local regulation on digital logic cards, eliminating the distribution problems
association with single-point regulation. The devices are available in two standard transistor packages. In the solid-kovar TO-5 header, it can deliver output currents in excess of 200 mA, if adequate heat sinking is provided. With the TO-3 power package, the available output current is
greater than 1A.
Specified to be compatible, worst case, with TTL and DTL
Output current in excess of 1A
Internal thermal overload protection
No external components required
